HAT-POUNCING MACHINE.

SPECIFICATION forming part of Letters Patent No. 415,243, dated November 19, 1889.

Application filed August 16, 1887. Seal No. 2117,076. (No model.)

T0 all wront it imag] concern:

Be it known that I, RUDOLF EICKEMEYER, of Yonkers, in the county of lVestchester and State of New York, have invented certain new and useful Improvements in Hat-Penneing Machines; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description of my invention.

Hy said improvements have been devised with special reference to their use in that type of machines known as the Taylor pouncingmachines, disclosed in E. B. Taylors United States Letters Patent, October 21, 1879, No. 220,889, and October 5, 1880, No. 232,860. Said machines have been termed self-feeding, because the feeding` operation is performed by the pouncing-eylinder, and While some of my said improvements are restricted thereto other features are applicable as well to machines heretofore devised by me, and

especially to such as were disclosed in my United States Letters Patent, April 19, 1881, No. 240,311. In said prior Tay-lor machines provision was made for variably retarding the feeding motion of the hat-body, and certain portions of my invention relate to specially-devised means for that purpose, and also to so regulate the retardation that during the pouncing operation the hat-body may be completely under the control of the operator. For attaining these ends I employ with the pouneing cylinder adj ustably yielding friction-clamps, and these are so mounted with relation to said cylinder and the hatsupport that while the hat is frictionally en'- gaged by two clampingsurfaces under a certain normal or predetermined pressure the operator is enabled to vary the location of the pressure in such a way that the hat will be fed or rotated in lines concentric to its longitudinal center whether the brim, the side crown, or the tip of the hat is being` pounced.

In hat-pouncing machines as heretofore constructed the lnounciiigroller shaft and its bearings and the hat-support and its foundation present more or less obstruction to the free and desirable movement of a hat-body during the pouncing of side crowns, and this I have wholly obviated by mounting the hatsupport upon a peculiarly-formed lever, which enables thehat-support and the immediatelyunderlying devices on which it is mounted to be located wholly within the hat-body and to afford beneath said support a free clear space to be occupied by the lower or pendent portion of a side crown and brim, while the upper 01' opposite portion of the brim stands vertically in front of the pouncing-cylinder, and the side crown is between the hat-support and the pouncing-surface of the cylinder. This portion of my improvement can be proitably employed in machines of various types. Gele tain other minor features have been devised by me,and after fully describing a machine embodying all of my said improvements, and as illustrated in the accompanying drawings, the features deemed novel will be duly speci fied in the several clauses of claim hereunto annexed.

Referring' to the three sheets of drawings, Figures 1, 2, and 8 illustrate one of my iinproved machines, respectively in front, rear, and end elevation, the main driving-shaft being omitted in Fig. 1. Fig. 4, Sheet 1, is a rear view of the hat-support detached and on an enlarged scale. Fig. 5 is a top view of said hat-support. Fig. 6 is an end view of said support, a part of the pouncing-cylinder or cutting-roller, and the frictional clamping devices, together with a portion of a hat, shown in section, as if undergoing the opera-tion of pouncing. Fig. 7 is a top view of a lever, by which the lower friet-ional clamping-jaw is in part controlled or supported. Figs. 8 and 9 illustrate the frictional clamping device in dilfer'ent positions of adjustment, as when pouneing a side crown, as in Fig. 8, and when pouncing a tip, as in Fig. 9. Figs. 10 and 11, Sheet 2, illustrate the pouncing-cylinder or cutting-roller detached, respectively in Aend view and section.

The frame A may be variously formed, so long as it affords suitable bearings and supports for the various working parts of the machine.

The main driving-shaft B is provided with tight and loose pulleys.

The cutting-roller or pouncing-cylinder C is mounted on a shaft a, having a pulley a',

IOO

which is belted to a large pulley a2 on the main driving-shaft. This roller has a pouncin g-surface parallel with its axis, and its abrasive fabric is secured thereto, as illustrated l and link b3, is similar to a corresponding portion of the machine shown in my said Let ters Patent No. 240,311; but said lever in this machine is novel as to its form and as to the arrangement of its upper end with relation to the pouncing-cylinder and hat-support. This lever E has a short vertical portion, to which the hat-support is directly bolted, a downwardly-inclined portion projecting beyond the outer end of the cutting-roller and parallel with a prolongation of its axis, and a vertical portion rectangular to the adjacent portion of the lever, which thence extends inward and downward to its pivot. ln other words, the outer end of said lever is hookshaped and affords an ample hat-receiving space at E', so that when the side crown of a hat is being pounced the tip will be vertical, and the pendent portion of the side crown horizontal and with its brim freely occupy the space E', as is fully indicated in Figs. 2 and 8, wherein a hat is shown in section in dotted lines with the brim at c, side crown at c', and the tip at c2, and the hat-support with its immediately-underlying devices, and the end of said lever is wholly within the hat and a part of the brim in front of the pouncing-roller.

The hat-support D is of a novel form of special value, in combination with a pouncing-cylinder operated as in this machine. As is clearly indicated in Fig. 6, the upper surface is cut away at d a little at one side of the dot-ted line d', which indicates the vertical axial plane of the pouncing-roller, so that ample space between said support and the cutting-line of said roller is afforded for the reception of frictional clamping-jaws. The upper clamping-surface is afforded by the under side of the curved friction-plate e operating as an upper jaw, and this is iirmly secured to the frame of the machine bymeans of bolts or screws passing through an arm c', preferably integral with said plate. The lower clamping-surface is afforded by the top edge of a T-shaped bar f, which operates as a lower jaw, and is supported and pivotally mounted at its shank f by means of a rectangular lever g, having a pivot-tip g', a hole g2, and a bearing-edge g3 at the end opposite its pivot. A pendent screw g4, secured to the under side of the support D, passes loosely through the hole g2 in lever g, and beneath said lever an expansive spiral spring g5 encircles said bolt, abuts against the under side of the lever g, serves for a fulcrum therefor, andit is rendered adjustable by means of the thumb -nut g. It will be readily obvious that with a hat, as at c, interposed between the plate f and bar g, it will be frictionally clamped with yielding pressure in proportion to the expansive force of the spring, and that this can be varied by means of the thumb-nut, thus enabling the operator to readily arrange for the desired degree of pressure necessary to properly'retard the rotation of a hat toward the pouncing-roller, the latter being driven in the direction indicated by an arrow thereon in Fig. (i. As thus far described, it will be seen that the frictional surfaces of the plate e and bar f will be maintained parallel with each other, and this is essential in pouncing certain portions of a hat; but in pouncing other portions, and while changing from one portion to another, it is important that one or both of said surfaces be tiltedin the line of the axis of the pouncing-roller. This is provided for by providing the friction-bar f below its supporting pivotalpoint with a pendent tail-piece f2, and with this serving as a handle the operator would be enabled to tilt said bar by hand and thus vary the angular adjustment of the face of the lower jaw with relation to the coincident face of the upper jaw. I have, however, provided for the control or angular adjustment of said bar by the foot of the operator.

The tail-piece f2 of said bar is` coupled to a treadle h, as follows: The treadle-lever h is ofthe bell-crank form, and its upper end is pivoted to a link or rod h2, which slides in a guide h3 on the hat-support lever E. On said rod there is an expansive spiral spring h4, which, by abutting againstthe guide-bear ing'h3 and against an adjustable sleeve h5 on said rod, forces the latter rearward toward the treadle-lever. The outer end of said rod is pivoted to a vertical lever h6, (also mounted on said main lever E,) and this is jointed to a link 7N, (see Fig. 8,) which in turn is pivoted to a pair of links hs 77,9, one of these being pivoted at its foot on the lever E and the other to the lower end of the pendentvtailpiece f2 of the friction bar or jaw f. The link It? extends at its lower end beyond its pivotal point, as at hw, and an adjusting or stop screwt' so abuts against its end as to restrict the rearward longitudinal movement of said link in opposition to the force of the spring h4 on the treadle-rod h2. The rear end hw of said link h? is guided in a block supported by a screw hu.

Now, referring to Fig. 8,it will be seen that the operating-surface of the friction-barf is parallel with the under surface of the friction-plate e, and that the side crown c of the hat is clamped evenly, as when the foot of the operator is on the treadle 7L. As said treadle is permitted to rise the friction-bar begins to tilt, causing the frictional pressure to be restricted to, or at least greater at, the outer end of the bar, and closely adjacent IOO .IOS

IIO

to the center of the tip c2 of the hat; thus by varying the location of main points of pressure causing the hat while being rotated by the pouncing-cylinder to rotate in lines concentric to the axial center of the hat Whether pouncing the brim c, side crown c', or tip If no treadle 7L were used, the pivoted clamping-jaw and the stop-screw 'i would be of practical value, the position of said jaw being then varied by the hand of the operator.

In operation, instead of introducing the hat for pouncing from the right hand toward the left, as in my prior machine of Patent No. 2i0,3ll, the hat is entered from the left-hand side in my new machines, and, whileI prefer to have them thus arranged, they could be reversed in this respect without in any manner affecting my invention. The hat-support being in a slightly-lowered position a hat-brim is introduced between it and the pouncingroller and t-he lever E raised by depressing the treadle ZP. The brim is thus clamped between the upper jaw or plate c and the lower jaw or bar f before the hat is carried into operative contact with the pouncing-surface, because the bar or jaw f is normally projected above the top or operative surface of the hatsupport by the spring g5. As soon as the pouneing-eylinder begins to operate the hat is revolved or fed by the drag thereon by the cutting-surface, and said movement of the hat is retarded by the frietional clampingjaws, and this retardation can be made more or less, according to the force exerted by said spring g5, it being understood that the stopscrew b restricts the'upward movement of the lever E and prevents the hat-support from being unduly forced toward the pouncing-surface. In order that the hat should be properly rotated while pouncing the brim, very slight pressure is applied to the treadle 7L. After pouncing the brim the hat is gradually guided inward upon the hat-support until the side crown rests thereon, pressure then being gradually removed from the treadle 7L; but said pressure is again applied gradually, as the hat is guided upon the support from the side crown to its square and tip, and after the latter has been pouuced the hat is gradually guided back, the clamping-jaws being similarly actuated by the t-readle h, but in a reversed order, while the hat is being guided out of the machine. Now, it will be readily obvious that efficient retardation of the hat will result from the use of the spring-actuated lower jaw and the upper jaw or clamp-plate, the hat being then wholly guided by hand. If, however, the lower jaw have a tail-piece or handle, as shown, the guiding of the hat can be more readily performed by tilting the lower jaw or clamp-bar f by hand; but the most convenient', desirable, and efficient service can be performed by using the treadle h.

In no prior pouuciug-machine known to me wherein, as in this, a hat can be pounced all over at one operation has it been possible to pounce side crowns without having the adjacent portions of the brim strained and whirled against the pouncingroller shaft or its bearings near the roller; but now the side crown can be pounced while the adjacent portion of the brim is located and rotated in a more or less vertical position in front of the pouncing roller, thus obviating distortion of the hat at the band or junction of the side crown and brim.

Having thus described my invention, I claim as new and desire to secu re by Letters Patentj l. The combination, substantially as hereinbefore described, of a pouncing or cutting roller which moves or feeds a hat during the pouncing operation, a hat-support for presenting a hat'to the pouncing-surface, a pair of clampingjaws, operating with yielding pressure, closely adjacent to said pouncingsurface, and the hat-support for frictionally engaging with a hat and retarding its movement during the pouncing operation.

2. The combination, substantially as hereinbefore described, of a pouncing-roller, a pair of clamping-jaws, and a hat-support having one of said jaws attached thereto, substantially as described, whereby said support and jaw will be wholly within a hat while its tip and side crown are being pounced.

3. In a pouncing-machine wherein the feeding movement of a hat is caused by the pouncing cylinder or roller, the combination, substantially as hereinbefore described, of a yielding clamping-jaw co-operating with a second jaw located closely adjacent to the cutting-line of said roller.

4. In a hat-pouneing machine, the combination, substantially as hereinbefore described, of a cutting-roller which pounces and also feeds or moves a hat toward it while pouncing, a stationary clamping-jaw closely adjacent to the cutting-line of said roller, and a movable clamping-jaw having its face angularly adjustable with relation to the face of the stationary jaw, whereby a hat during the operation of pouncing may be retarded by a varied frictional engagement of said jaws and enable the pouncing-roller in feeding the various parts of the hat to cause said part-s to rotate in lines concentric to the axial center of the hat.

5. In a hat-pouncing machine, a pouncingroller, a hat-support, and a lever below and projecting beyond the outer end of said roller and hook-shaped, substantially as described, for affording beneath the hat-support and that portion of the lever on which it is immediately mounted a free and unobstructed space for pendent portions ofa hat while carried on the support during the operation of pouncing a side crown and for locating the adjacent portion of the brim in front of said roller.

6. The combination, substantially as hereinbefore described, of the pouncing-roller, a stationary clamping-jaw, a movable clamping-jaw, and a treadle for varying the augu- IOO IIO

lar adjustment of the face of said movable jaw with relation to the face of the stationary jaw.

7. The combination, substantially as hereinbefore described, of the pouncing-roller, a stationary hat-clamping jaw closely adjacent to the cutting-line of said roller, a hat-support mounted on a lever for moving it toward and from said roller, and a yielding clamping-jaw, also mounted on said lever, for co-operating with said upper clamping-jaw, whereby in presenting a hat to the pouncing-roller said jaws frictionally engage with the hat while the latter is presented to the pouncingsurface. l

8. The combination, substantially as hereinbefore described, of a pouncing-roller, a stationary clamping-jaw adjacent to the cutting-line of said roller, a hat-support, a movable lower clamping-jaw, a lever on which said hat-support and said movable jaw are mounted,a treadle for lifting and lowering said support, and a treadle for Varying the angular adjustment of the face of said movable jaw with relation to the face of said stationary jaw.

l0. The combination of the hat-support, the pendent adjusting-screw, its nut and spring, the presser bar or jaw, and t-he lever pivoted to said jaw, fulcrumed on said screw and spring and bearing against the under side of the hat-support, substantially as described. Y

1l. The combination of the pouncing-roller, the hat-support having a bearing-face at the cutting-line of the roller and recessed at one side of said face for accommodating a stationary clamping-jaw, and a yielding clamping-jaw normally projected above said bear- 45' ing-face, substantially as described.
